OIL-PRESS CLOTH.

SPECIFICATION forming part of Letters Patent No. 679,182, dated July 23,1901.

Application led September 13, 1900.

To a/ZZ whom t may concern.-

Be it known that we, JOSEPH MOOARRON, CHARLES MOCARRON, and JOHN J.MOCAH- RON, citizens of the United States, residing at New Orleans, inthe parish of Orleans and State of Louisiana, have invented new anduseful Improvements in Oil-Press Cloths, of which the following is aspecification.

Our invention relates to improvements in oil-press cloths such as arewoven of long animal hair and designed for use in cottonseed and otheroil-extracting presses; and it consists in a certain peculiar cloth, thenovelty, utility, and advantages of which will be fully understood fromthe following description and claims when taken in conjunction with theaccompanying drawings, in which- Figure 1 is a plan view of an oil-presscloth woven of long animal hair in accordance with our invention; andFigs. 2 and 3 are sections of the same taken in the planes indicated bythe broken lines 2 2 and 3 3, respectively, of Fig. 1.

Referring by letter to the said drawings, A A are the warp-threads ofour improved cloth, and B B are the weft-threads. These threads are eachcomposed of horse-tail or other long, hard, coarse, and strong animalhair and cattle-tail or other long, soft, and pliable animal hair in theapproximate proportions of two-thirds of the former to onethird of thelatter.

In the making of the threads the crude horse-tail or equivalent long,hard, and strong animal hair and the crude cattle tail or equivalentlong, soft, and pliable animal hair are thoroughly intermingled or mixedin a mixer, picker, and hackler or other suitable apparatus in theapproximate proportions stated and are then Spun. The threads intendedfor the warp and those intended for the woof of the cloth are given thesame amount of turn or twist and are similar as to size incross-section, hardness, and strength.

In making the cloth the warp-threads and weft-threads formed in themanner described are interwoven in a loom or by hand, preferably in suchmanner that there is about twothirds as many weft-threads to the inch aswarp-threads. This feature is clearly illustrated in Fig. 1 of thedrawings, in which Serial No. 29,941. (No specimens.)

there are six warp-threads to the inch and four weft-threads.

The cloth may be and preferably is provided with a suitable selvage oredge binding with a view of preventing Vdisintegration thereof; but suchselvage or edge binding forms no part of our invention, and we havetherefore deemed it unnecessary to illustrate the same.

By virtue of both the warp and weft threads of the cloth being made ofhorse-tail or other long, hard, and strong animal hair and cattle-tailor other long, soft, and pliable animal hair, as described, they areuniform in strength, and the cloth is rendered as strong anddnrable inthe direction of its width as in the direction of its length. As aresult of the warp-threads and weft-threads being uniformly twisted theone kind are as hard as the other, and hence are enabled to offer eachto the other a uniform amount of resistance, which condnoes to thestrength of the cloth and prolongs the usefulness of the same. Theembodiment of horse-tail hair in both the warp and weft threads conducesto the strength of the same, while the embodiment of the cattle-tailhair in the threads enables them to give to each other and materiallylessens the liability of one cutting or otherwise injuring the otherwhen the cloth is subjected to pressure.

The arrangement of two-thirds as many weft-threads Ato the inch aswarp-threads equalizes the strength and durability of the cloththat isto say, increases the strength of the cloth in the ,direction of itswidth and renders it almost if not quite as strong in such direction asin the direction of its length.

We are well aware of the patent of one Werk, No. GiOOS, of January 2,1900, which discloses an Oil-press cloth consisting of a fabric composedof animal long hair, the hairs forming the warp-threads of the fabricbeing hard, stiff, or coarse, and having a hard twist, and the hairsforming the weftthreads being soft pliable hair, and having a softtwist. We are also aware of the patent of one Hanse, No. 611,316, ofSeptember 27, 1898, wherein is shown an oilpressmat,which is peculiar inthat the warp-threads at the middle portion of the fabric are crowdedto- IOO gether more than at the edges of the fabric andare in greaternumbers at the middle than at the edges, this with a View of preventingthe mat rapidly wearing away at its middle portion, which is subjectedto the greatest strain incident to the use of the mat. We therefore makeno claim to such constructions; but

What we claim, and desire to secure by Letters Patent, is-

1. An oil-press cloth, comprising warpthreads and weft-threads; the saidwarp and weft threads being each composed of long hard coarse and stronganimal hair, and long, soft and pliable animal hair mixed together,substantially as speciied.

2. An oil -press cloth comprising warpthreads and weft-threads; the saidWarp and weft threads being each composed of horsetail hair, andcattle-tail hair mixed together,

being each composed of long, hard, coarse and strong animal hair, andlong, soft and pliable animal hair mixed together, substantially as andfor the purpose set forth.

' In testimony7 whereof We have hereunto set our hands in presence oftwo subscribing witnesses.
